China is diabetes big country, is all the hat in the whole world all the time on diabetes population absolute number, currently, China 18
Year old or more in adult's sample, the diabetes estimation illness rate diagnosed according to international newest clinical criteria is
11.6%.This data has caused extensive concern both domestic and external.Although Chinese health of the masses consciousness is enhanced in recent years,
Diabetic's number quickly increases the change that this trend does not obtain essence.
It is well known that diabetes are a kind of chronic metabolic diseases, life-long therapy is needed, and insulin therapy is diabetes
An indispensable part in drug therapy.Either type 1 diabetes patient or diabetes B patient, with islet cells
The gradual decaying of function will all face the circumstances for receiving insulin therapy.Receiving injection of insulin treatment may need to note daily
It penetrates for several times, injection of insulin is typically using hypodermic injections such as insulin syringe, insulin injection pen and insulin pumps.Just
Under normal physiological condition, insulin enters liver from pancreatic secretion through portal system, and subsequently into peripheral circulation, it is high to form liver
In the concentration gradient of peripheral blood circulation.Subcutaneous insulin injections can form the insulin concentration that peripheral blood circulation is higher than liver
Gradient, this is not inconsistent with normal physiological conditions.The shortcoming brought is：It is easy to form hyperinsulinism blood trouble, be easy to happen low
Blood glucose.
But if insulin can be absorbed into liver through intraperitoneal administration through peritonaeum-portal system, liver is formed higher than outer
All sanguimotor concentration gradients, meet physiological condition, bring the advantage that：Hypoglycemic incidence is reduced, it is different to correct lipid metaboli
Often, diabetic complication is prevented.
Utility model content
For the prior art, the utility model provides a kind of intraperitoneal administration indwelling equipment, in the therapeutic process of insulin

Diameter is matched with the outer diameter of the injection head of 1~5ml syringes；The second injection head includes the tube core being arranged in pipe cap, institute
It states to be threadedly coupled between pipe cap and the first injection head, is equipped between the bottom of the tube core and the bottom surface of the counterbore close
The top of packing, the pipe cap is equipped with groove, is inlaid with silicon rubber plug in the groove, is set at the top of the silicon rubber plug
There are dust cap, the dust cap to be equipped with lasso, the lasso is sleeved between the external thread section and butterfly piece of the second injection head
Shaft part on；The first injection head and the second injection head use the transparent material of medical grade.
Further, on the flexible conduit it, is being equipped with oversleeve positioned at the side of butterfly piece, the material of the oversleeve is doctor
Outer diameter with the terylene of grade, the oversleeve is 3mm.
The flexible conduit includes internal layer and outer layer, and the material of the internal layer uses the polyethylene of medical grade, the outer layer
Material use medical grade polyurethane.
The first injection head and the second injection head use the makrolon of medical grade.
Compared with prior art, the utility model has the beneficial effects that：
The administration indwelling equipment for using the utility model to design, wherein the flexible conduit of administration can Preserving time in abdominal cavity,
For long-term intraperitoneal administration.Insulin abdominal cavity can be used for for diabetic.
The utility model can solve the demand of intraperitoneal administration, since the diameter of flexible conduit is thinner, have skin wounds
Small advantage.In addition, the rubber dust-proof plug on the terylene oversleeve and injection head that are arranged on flexible conduit can prevent cause of disease micro-
Biology enters abdominal cavity.
